When you export views and sheets to DGN, Revit LT objects and features are mapped to their MicroStation counterparts where applicable.
| Revit LT | MicroStation | Notes |
|---|---|---|
| Geometric Elements | Geometric Elements |
Includes detail lines, model lines, and 2D presentations of Revit LT elements. |
| Colors | Colors | Colors are matched as closely as possible. Categories set to export with index color are translated directly to the DGN color index. If true color is used and a direct match of RGB values is available in the DGN color index, the colors are also mapped directly. If a true color match is not available, an RGB value is added to the DGN color index. |
| Line Patterns | Line Styles | Custom linetypes are unsupported and could produce unexpected results. |
| Families | Cells | Families are exported as shared cells. |
| Model Text, Text Notes | Lines, Text, Text Styles | Model text is exported as lines; text notes are exported as text. |
| Dimensions, Dimension Styles | Dimensions, Dimension Styles | The size, spacing, style, and shape of dimensions may vary slightly. The correct dimension values are always maintained. |
| Raster Images | Raster Images | BMP, TIF, PNG, and JPG file types are supported. |
| Links | DGN References | Depending on the export option specified, referenced RVT and DWG files are either converted into DGN files or combined into a single DGN file as cells. |
| View | DGN Design Model | The view in a Revit LT project file is converted into a DGN file. |
| Sheets | DGN Sheet Model | Upon export to V8, sheets are converted into sheet models in the DGN file. Because V7 only supports one model, several DGN files may be exported: one for the model and others for the sheet views in the Revit LT project file. |
| AEC Objects | Imported objects from AutoCAD Architecture are not supported. |
